Aliphatic hydrocarbons such as fatty alcohols and petroleum-derived alkanes have numerous applications in the chemical industry. In recent years, the renewable synthesis of aliphatic hydrocarbons has been made possible by engineering microbes to overaccumulate fatty acids. However, to generate end products with the desired physicochemical properties (e.g., fatty aldehydes, alkanes, ...

Cattle can synthesize L-ascorbic acid (or Vitamin C) from either D-glucose or D-galactose through glucuronic acid pathway in the liver. L-Ascorbic acid present in cattle diet is almost totally destroyed by rumen microorganisms making them essentially dependent on its endogenous synthesis, which is assumed sufficient to meet the physiological requirement. ...

Abstract The infective larvae of Teladorsagia circumcinta have a protective sheath which is lost soon after they reach the rumen of the sheep. Incubation in vitro with 50 mM imidazole caused more than 75% of L3 T. circumcincta to start exsheathing within 2 h. The initiation of exsheathing was less ...

The recently described bacterium "Candidatus Methylomirabilis oxyfera" couples the oxidation of the important greenhouse gas methane to the reduction of nitrite. The ecological significance of "Ca. Methylomirabilis oxyfera" is still underexplored, as our ability to identify the presence of this bacterium is thus far limited to DNA-based techniques. Here, we ...

Rhamnolipids have multiple potential applications as "green" surfactants for industry, remediation, and medicine. As a result, they have been intensively investigated to add to our understanding of their biosynthesis and improve yields. Several studies have noted that the addition of a fatty acid cosubstrate increases rhamnolipid yields, but a metabolic ...
